ERNST IBEBIE, OF LA FARGA, SAN QUIRICO DE BESORA, SPAIN.

SPINNING AND DOUBLING MACHINE.

To all whom it may concern:

Be it known that I, ERNST BEBII J, a citi- Zen of the Republic of Switzerland, residing at La Farga, San Quirico de Besora, Province of Barcelona, Spain, have invented certain new and useful Improvements in Spinning and Doubling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Referring to the drawings in which like parts are similarly designated, Figure l is a diagram illustrating the doubling action. Fig. 2 is a view illustrating the use of one form of my invention. Fig. 3 is a vertical central section of one form of my invention. Fig. 1 is a vertical section and Fig. 5 is a plan showing another form of my invention.

Spinning and doubling machines are known which give a double twist to a thread, during its course from a winding oflf reel to taking up spool. The essential feature of these consists substantially in the thread to be treated being doubled back 011 itself on its way from the winding oif reel 1 (see Fig. 1) to the taking up spool 27 at a place is and at this turning point is turned, while the thread is relatively held fast or retained at two points a; and 3 of which one, 1 is located between the turning point 70 and the taking up bobbin 27 and the other between the turning point 70 and the winding off reel 1, so that, for each turning of the turning point each piece of thread m--7c and 1 ']c receives a twist between the turning point 70 and the fixed point 02 or y. In these machines either the reel 1 or the fliers 17, 18, must be stationary, although they are mounted on part-s which rotate. In such spinning and doubling machines hitherto employed the loosely mounted part is rendered stationary by its being connected by means of a differential gear with a rotating part on which it is mounted, so that the rotation is arrested.

Now in order to attain in a simpler manner the stationary condition, and to avoid the differential gear which expends a portion of the driving power, and thus to be able to realize a greater number of revolutions, by the present invention the stoppage of the respective part is produced by the Specification of Letters Patent.

spindle axis being inclined, and by a onesided loading of the part which is to be rendered stationary.

The object of the invention is further shown in the accompanying drawings in Figs. 2 and 3 with a stationary winding oif reel and circulating fliers, and in Figs. 4c and 5 with a rotary winding 01f reel and stationary fliers.

In the example of construction shown in Figs. 2 and 3 the doubling takes place at the winding 01f reel. 1 is the winding off reel, 2 a spindle revoluble in the part 3 of the machine. This spindle 2 has a cord pulley 4 for its compulsory operation and a disk 5 which has on its edge a thread eyelet 6. The spindle 2 above is extended into a hollow part 7 of the spindle. Around the spindle 7 above the disk 5, a bearing cup 8 of a ball bearing is fast on the disk. The other bearing cup 10, loosely resting on the balls, carries a shaft 11 loosely surrounding the spindle 7. On this shaft 11, a sleeve 12 of the casing 13, Which is loaded onesidedly with a weight 14: and carries the cop, is mounted, which avoids breakage of the thread in forming the cops. The winding off reel 1 rests on the bottom of the casing 13 and carries above a head-piece 15. On the headpiece 15 a ring 16 is lightly mounted which has an elbow arm 17 and a T shaped arm 18. These parts form the flier. The upper sleeve-shaped part of the ring carries a thread eyelet 19. The elbow arm 17 carries a brake lever 21 pressed by a spring against the reel 1, and the other arm 18 carries a guide slot 22 and an open guide eyelet 23. The spindle 2 and there with the entire apparatus with the winding off reel 1 stands in an inclined position. The weight has thus a tendency to hold the part 13 with the reel resting thereon, in the position shown in Fig. 3.

The thread guidance is as follows: Several raw threads 24 pass from the reel 1 through the thread eyelet 19, ring 16 and headpiece 15, the hollow spindle 7 down to beneath the disk 5, from there passing through a lateral perforation 25 away under the disk 5, they are conveyed upward through the thread eyelet 6 to the center point (Fig. 3) lying in a prolongation of the central line of the spindle 2, and formed by the two rollers 26 or a loop or sows tail, and from there directly to the revolving twist taking up reel 27. If tension be produced on the thread 21 by the rotation of the rollers 26, the parts 18 and 16 revolve and wind off the raw thread composed of several untwisted threads from the stationary reel 1. The thread now receives its first twist between the eyelet 19 and perforation 25. which twist is equal to the number of revolutions of the spindle increased or diminished by the number of revolutions of the winding off parts 18, 16, according as to whether the bobbin is mounted in such a way that the parts 18, 16, for winding oil the yarn revolve in a direction opposite to or similar with that of the spindle. The thread receives its second twist between the thread eyelet 6 of the disk and the supporting point 28 which may be formed by a glass rod or loop or sows tail. Compared with the diagram, Fig. 1, the first fixed point corresponds to the thread eyelet 19, the second fixed point 1 corresponds to the glass bar 28 and the reversing and turning point corresponds to the perforation 25 or to the eyelet 6 of the disk.

In the examples of construction shown in Figs. 4: and the reel 1 rotates and the casing 13 is stationary. 1 is again the reel, 2 the spindle revolubly mounted in the part 3 of the machine. 1% the cord pulley, 5 the disk, and G the thread eyelet on its edge. 8 is the one half of the ball bearing which is firmly connected with 5 and 4; the other half 10 of the ball bearing is firmly connected with the hollow sleeve 11 which lies loosely around the upper spindle part 7 and has a weight 1+1 on which the cage 13 is mounted. The reel 1 is loosely mounted on the sleeve 11. Now 23 is a flier engaging on two bars 13 of the cage 13, which lie parallel to the reel 1, which flier has an eyelet 2;- b and a slot 23 (Fig. 5) leading to the eyelet 23". N ow the thread 2t passes from the reel 1 through the eyelet 23 of the flier 23, eyelet 22, eyelet 1S), hollow spindle T, passage 25, and the eyelet (3 to the taking up reel. The piece 245" of the thread always receives by the flier 23 a position rectair gular or approximately rectangular to the reel 1. An arm 29 is pivoted on the cage bar 13 so that, if the yarn should by chance entangle with the cage 13 and thus turn the latter by overcon'iing the weight 11. said bar will come into the position normally occupied by the bars 13 and the arm 29 swing on its pivot in the direction indicated by the arrow, and as shown in dotted lines, oncounter a stop 30 placed at a suitable distance in order to prevent any further rotation of the cage 13. The brake 21 is mounted on a post 17 secured in the cage ring 13. A coil spring 22 secured at one end to the post acts with its other end against the brake 21.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. In a spinning and doubling machine the combination with a rotating inclined spindle; of a cage revolubly mounted on the spindle; a weight on one side of the cage to hold it against rotation and two elements surrounding the spindle, one of which a flier and the other a reel, one of said elements being revoluble with respect to the other.

2. The combination in a spinning and doubling machine for giving a double twist, of an upwardly inclined spindle, means for rotating the spindle, a cage revolubly mounted on the spindle, a weight on the cage, eccentric to the spindle axis and a flier loosely surrounding the upright side bars of the cage, substantially as described and shown.

3. The combination in a spinning and doubling machine for giving a double twist, of an upwardly inclined spindle, a disk fast 011 the lower part of the spindle, a longitudinal perforation in the spindle, extending beneath the disk laterally into a transverse perforation, a thread eyelet fixed on the edge of the disk, a ball bearing on the disk, a cage with a sheath or holder loosely engaging around the spindle, and resting on the ball bearings, a weight eccentric to the middle line of the cage and fast on the same, side bars on the cage lying parallel to the middle line of the cage, a flier loosely engaging two side bars, a thread eyelet over the flier fast on the cage, and a reel loosely revolubly mounted on the sheath of the cage, substantially as described and shown.

4. The combination in a spinning and doubling machine for giving a double twist thread, of an upwardly inclined spindle, means for rotating the spindle, a cage revolubly mounted on the spindle, a weight on the cage eccentric to the spindle axis, side bars 011 the cage lying parallel with the middle line of the cage, and one of them on the side opposite the weight, a part of this bar being revoluble and adapted to be folded back at an angle to the axis of the bar, sub stantially as described and shown.

In a spinning and doubling machine the combination with a rotating inclined hollow spindle, a thread eye distanced from and carried by the spindle, of a cage revolubly mounted on the spindle, a weight on the cage eccentric to the spindle to hold it against rotation, and two elements surrounding the spindle one of which is a flier and the other a reel, one of said elements being revoluble with respect to the other and a brake to retard the revoluble element.

(5. In a spinning and doubling machine the combination with a rotating inclined hollow spindle; of a thread eye radially distanced from and carried by the spindle and a thread eye in alinement with the upper end of the hollow spindle, a cage revolubly mounted on the spindle, a ball bearing between the cage and spindle, a weight to eccentrically load the cage, and two elements surrounding the spindle one of them a reel and the other a flier, one of said elements being revoluble with respect to the other and a spring urged brake to retard the revoluble element.

7. In a spinning and doubling machine, an inclined spindle axis, a cage revolubly mounted thereon, a rod substantially parallel to the spindle axis, an unbalanced pivoted lever mounted on the rod and means on the cage to tend to maintain said rod or lever at the highest point of rotation of the cage and a fixed stop at the lowest point of rotation of the frame against which said lever will strike by reason of the rotation of the frame and the movement of the lever on its pivot.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
